Sound absorption panels for unside stand??

[banditpowdercoat]

Has anyone experimented with sound absorbing panels fro inside the stand? Just got a Aqua C Urchin skimmer, and with the Drain(durso is quiet but bubbles in sump are not) Was thinking of somehting to deaden the sound? My stand is MDF thats covered in black plastic veneer which makes it echo and sound louder...

What you all use? Brand names so I can go to Rona and get some

Thx in advance
